Moving to Fixed from Tracker

We've had huge success over the past 3 years with a 50:50 deal on our home whereby we had a low tracker rate for half the mortgage but also fixed half the mortgage for 5 years at 3.78%. Swings and roundabouts for when rates were sky high and now that they are very low again.

I've been watching the fixed rates and they are becoming very attractive again. I have a small number of investment properties and I am tempted to fix given that I do expect inflation / high interest problems in 18months to 2 years time. The dilemma for me is the fact that these are tracker mortgages and since these have been all been withdrawn, there is an argument for not throwing away what can't be replaced. Just not sure what to do?? Fix or track?

Tracker to save you the most (maximum) amount of money over the life of the mortgage.
Fixed to TRY and beat the bank, possible save more in the short term but loose out when the fixed rate ends and you are at the mercy of the banks new fixed rates or SVR. Tracker rate will be gone if your fix again.
Your fixed rates worked out well in the past, but dont expect them to always work out so well, banks dont lose money very often.
